Is it possible to implement Keccak and Blake2 hashing in parallel?

Question

Cryptography

I am not related to IS, but a programmer. I read that Etherium and Decred cryptocurrencies can be mined at the same time, and that these minings do not interfere with each other. The first cryptocurrency calculates Keccak hashes, the second - Blake2. Let's assume that only hashing occurs during the mining process (for simplicity). Do you know if it is possible to somehow hash simultaneously on one video card so that the processes do not interfere with each other?
